The Center for Astrostatistics is an interdisciplinary center to serve the astronomy and statistics communities world wide, in part through a multifaceted Web site. The cross-disciplinary center's main mission is to bring advances in statistics, including both long standing and novel methods, into the toolbox of astronomy and astrophysics. It is an ongoing service and outreach center for the research communities.

The goals include:

• promoting applications and appropriate use of statistical thinking, practice, and data analysis in astronomy; and
• supporting the growth and development of interaction between the two research communities through series of workshops.

This effort complements the recent NSF focused research award to Professor G. J. Babu, supporting National Virtual Observatory-oriented research.

Web activities include the maintenance of a highly popular StatCodes site providing links to statistical codes and services on the Web, and a metasite archive of annotated links to selected methodological articles in astronomical and statistical literature applicable to astronomy. The site also will include research updates, informal reports by the center's associates, and training handbooks produced for the annual on-site workshops and tutorials.
